My invention relates to improvements in jump measuring devices fordetermining the height to which persons are capable of jumping upwardlyofi a floor, or the like, in either a standing or a running jump.

The primary object of the invention is to provide a simply constructed,inexpensive device for the purpose indicated which is adapted forinstallation on a wall, or the like, to be swung horizontally flatagainst the Wall when not in use, or, swung into outstanding projectingrelation to the wall for use when desired.

Another object is to provide a device of the character and for thepurpose above set forth which will not get out of order or become brokenas a result of rough usage to which such devices are usually subjected.

Other and subordinate objects, within the purview of my invention,together with the precise nature of my improvements will be readilyunderstood when the succeeding description and claims are read withreference to the drawing accompanying and forming part of thisspecification.

In said drawing:

Figure 1 is a view in perspective of my improved jump measuring devicein a preferred embodiment thereof swung into position for use;

Figure 2 is a fragmentary view in vertical section taken on line 2-2 ofFigure 1 and drawn to a larger scale;

Figure 3 is a View in perspective of a modified embodiment of myimproved jump measuring device swung into a position for use;

Figure 4 is a fragmentary view partly in side elevation and partly invertical section and drawn to a larger scale to illustrate in detail themanner in which the bars of the modified embodiment are suspended.

Referring to the drawing by numerals, and first to Figures 1 and 2,according to my invention, in the preferred embodiment thereof, a seriesof foot and inch indicating, fiat bars are provided, the foot indicatingbars being designated by the numeral I and the inch indicatin bars bythe numeral 2. The bars of the series, I, 2 are graduated in lengththroughout the series.

Means are provided for swingably suspending said bars I, 2 bycorresponding ends thereof in edge to edge spaced apart relation withlower ends stepped upwardly from the longest bar, for a purposepresently seen. The suspending means preferably takes the form of hinges3 at upper ends of said bars I, 2 and on one and the same side of saidbars, said hinges being suitably attached, as by screws 4, to a hangerarm 5, the arrangement being such that the foot and inch indicating barsI, 2 may be swung away from the hanger bar 5 in one in the samedirection only, the upper ends of said bars I, 2 abutting the lower edgeof the hanger bar 5 to prevent swinging of said bars I, 2 in theopposite direction from normal vertical position.

The hanger bar 5 is hinged at one end thereof, as at 6, to a bracketplate 1 adapted to be fastened to a wall 8, or other upright support, as

by screws 9 so that said arm 5 is swingable about a vertical axis, thearrangement being such that the hanger arm 5 may be swung toward thewall 8, as indicated by dotted lines in Figure 1, to position the sametogether with the foot and inch indicating bars I, 2 substantially fiatagainst the wall 8 in an out of the way position when not in use and,when it is desired to use the device, said arm 5 together with said barsI, 2 may be swung away from the wall 8 to dispose the arm in outstandingposition relative to the wall 8 with the foot and inch indicating barsI, 2 disposed substantially in acommon vertical plane at a right angleto said wall.

A turnbuckle rod I0 braces the hanger arm 5 against sagging on the hingeB. For this purpose, one end of the turnbuckle rod I0 is suitablysecured, as at II, to the hanger arm 5 adjacent to the free end of saidarm and inclines upwardly along the hanger arm 5 to the attachingbracket 1 with its other end swivelled, as at I2 in said bracket I forswinging of the turnbuckle arm I0 with the hanger arm 5.

As will be seen, the foot indicating bars I comprise the longest end barof the series and intermediate shorter bars of the series and these footindicating bars are designated on one side, as at I3 to indicate innumbers of feet different heights from the floor, orthe like, not shown,in consecutively numbered ascending order beginning with the longest barof the series.

The inch indicating bars 2 are designated on the same side thereof asthe foot indicating bars I to indicate in numbers, as at I4, multiplesof inches in a foot arranged in ascending order from the foot indicatingbars I to supplement in inch measurements the designations I3 on thefoot indicating bars.

As will be obvious, from the drawing, the foot and inch indicating barsI, 2 are swingable sidewise from normal vertical position, in thedirection previously indicated, with the designations the hanger arm l8and through which said rod 58 is extended supports said rodI'Lintermediate.
